摘要:
A white ink composition contains a white coloring material and a fixing resin component. The fixing resin component includes a styrene acrylic resin and a urethane resin at a mass ratio of the styrene acrylic resin to the urethane resin (styrene acrylic resin/urethane resin) of at least 1/10.
摘要:
A method for obtaining and evaluating a white color shielding degree of a white color printed material includes the steps of: measuring an L* value of the white color printed material; obtaining an integrated value of transmittance of the white color printed material in a visible light region; and obtaining the white color shielding degree from the L* value and the integrated value.

An ink jet printing apparatus includes a head that is provided with nozzle holes for ejecting ink, and a control unit that performs a plurality modes, and the plurality of modes includes a first image printing mode of ejecting white-based ink from the nozzle holes to adhere the white-based ink to a first area of a printing medium and a second area different from the first area to print an image, and a second image printing mode of substantially concurrently ejecting color ink and resin ink from the nozzle holes to contact and adhere the color ink and the resin ink onto the white-based ink of the first area to print an image, and ejecting resin ink from the nozzle holes to adhere the resin ink onto the white-based ink composition of the second area to print an image.
摘要:
An ink set includes a first ink that contains a white material and a first resin; and a second ink that contains a color material other than the white material and a second resin, wherein the first resin includes a component (A) causing cracks when resin of 0.5 g is dropped onto a slide glass and is dried at a temperature of 50° C. and a humidity of 0% RH for 10 minutes, and wherein the second resin includes a component (B) of at least one of polyolefin wax and ethylene vinyl acetate resin.
